Acrobat Pro 2024: Empty Sidebar / AcroCEF Render Failure on Apple Silicon (Standard User Account Issue)

Hello everyone,

I am facing a persistent issue with Adobe Acrobat Pro 2024 on macOS (Apple Silicon) where the editing sidebar becomes completely blank/empty when clicking "Edit PDF" or accessing specific tools.

After extensive troubleshooting and multiple sessions with Adobe support, I have isolated the exact behavior:

1. Not an installation corruption: Acrobat tools load correctly when running under the macOS root account, but fail on standard/admin user accounts.

2. Fresh Account Behavior: On a brand-new macOS admin account, the tools load once on the very first launch, but the sidebar goes permanently blank on the second launch (indicating an AcroCEF cache corruption or sandbox failure).

3. Exhausted standard fixes: I have already cleared caches, repaired disk permissions, removed AcroCEF folders, disabled 2D acceleration, cleared Saved Application State, and reset firewall settings.

4. No UI Workaround: Since the classic Acrobat interface toggle was removed from this build, there is no way to bypass the broken modern interface.

Running Acrobat from a root account is a major security risk, and the automated support chat keeps looping me through basic steps.

Has anyone found a working workaround or a preference fix for this AcroCEF rendering bug on Apple Silicon standard user profiles? Any advice from community experts or Adobe staff would be greatly appreciated.

Thank you!
